참여 물질

반응 단계

1-Propanephosphonic acid cyclic anhydride (5.76 g, 92 mmol, 5.38 mL) was added dropwise to a solution of 4-amino-3-(trifluoromethoxy)benzoic acid (1 g, 4.6 mmol), N-tert-butyl-3-(piperazin-1-ylmethyl)benzamide (1.3952 g, 5.1 mmol) and triethylamine (1.37 g, 13.8 mmol, 1.886 mL) in dichloromethane. The reaction was stirred at room temperature for 1 hour. The reaction was concentrated under reduced pressure and the residue was taken up with ethyl acetate, washed with water, sodium hydrogen carbonate and brine. The organic phase was concentrated under vacuum to afford the title compound (1.36 g).
